Enum Reorder 

pub enum Reorder {
    Allow,
    Deny,
    Retarget(usize),
}

A reorder guard’s verdict on a proposed row move (docs/list.md): consulted synchronously from the native drag’s validate hook, so the affordance (gap, insertion mark, forbidden cursor) reflects the answer while the user is still dragging.

Variants

Allow

Accept the drop where proposed.

Deny

Refuse the drop (the row springs back; most backends show a forbidden cursor live).

Retarget(usize)

Accept the drop, but at this row index instead of the proposed one.

Trait Implementations

impl Clone for Reorder

fn clone(&self) -> Reorder

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Reorder

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Reorder

fn eq(&self, other: &Reorder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
